Description[]

Size comparison of the 3 largest Australian theropods.
Since its discovery, Australotherizinn was considered one of the largest theropods ever discovered. Its long skull, neck, body, and tail gave it a length estimate of up to 19 meters long, making it one of the longest therpods ever with only Australospinus being longer. However, its thin frame gave it a lower weight estimate of 7-8 tons. Australotherizinn has the longest skull of any known theropod, with a length of 10 feet. The skull's lower jaw is lined with small sharp teeth. Australotherizinn has a very long neck for a theropod. It has a long thick tail. This dino also has the largest known forearms of any theropod that end in 3 very long 3 foot claws.
Habit And Feeding[]

Depiction of a fight between Australospinus and Australotherizinn.
Australotherizinn was most likely a specialized fish eater due to lts long narrow skull that could reach deep into the water and long claws that could do the same. Its skull was likely not very strong so it likely went after smaller fish then those the Australospinus likely caught. Australotherizinn may have also hunted small dinos such as the Trinisaura and Qantassaurus. It likely competed with Australospinus for food and territory as both were of similar size and ate similar things. Young Australotherizinn may have been targeted by Megaustralosaurus as full grown therizinn's were likely too much for the Mega's to take on. The Therizinn would have mostly relied on its large claws during a fight as with jaws were likely not strong enough and its teeth were too small.
